To ALL WHoM IT MAY ooNoERN; Y

Beit known that 1, ANDREW KBIEBEL, of Hereford, in the county of Berks,and State of Pennsylvania, have invented a new and useful Improvement inLifting-Machines; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a side view of my improved machine. l

Figure 2 is a. front view of the same.

Similar letters of reference indicate like parts.

My invention has for its object to furnish a simple, cheap, andconvenient machine, designed especially to enable the end of anendless-chain horse-power to be easily and conveniently raised by oneman, to receive the trestle, so as to give a proper inclination to theendless chain of the machine.

It consistsv in theconstruction, combination, and arrangement of thevarious parts, as hereinafter more fully described.

A is a post, which should be made of a length corresponding tothe heightto which the sills of the horsepower are to be raised.

'lhe post A is slotted longitudinally, from near its upper` to near itslower end, as shown in figs. 1 and 2, with two slots through 'thecentres of its sides, said slots intersecting each other at right anglesin the centre of the said post A.' The lower end of the post A may berounded olf, as shown in fig, 1, so as to be somewhat wedge-shaped, andmay be further secured from slipping by being provided withdownwardly-projecting spikes or prongs, as shown in iigs. 1 and 2. Ifdesired, the post may be made of four small square sticks of timber,properly secured to each other at the ends, and at suitable distancesapart. v

The post A, upon one side, is perforated with two rows of holes, .onerow being upon each side of the slot, and the holes of the two'rowsalternating with each other in height, as shown in iiggl, and in'dottedlines in fig. 2. Y l

B are pins, placed in the holes in the post A, to serve as fulcra to thelever C.

The lever C is made of such a size as to pass through and worknthe slotin the post A., at right angles to the direction of the pins B, and ofsuch a strength as to raise the frameof the horsepower. i

The forward part of the lever C has two notches formed upon its underside, at such a distance apart as to t upon the pins B, which passthrough the said post A, as shown in fig. 1. l'

To the lower side of the forward end ofy the lever C, midway between thenotches in said lever, is pivoted a hook, upon which is hooked thecentral link of the chain D,'thel ends of which pass out through theslot in the post A, which is at right angles to the 'slot in which thelever C works, as shown in the drawings, and hook.

upon hooks attached to the sills of the horse-power to be raised, asshown in red in 2. When thus arranged, by working the long arm or handleof the lever C alternately up and down, and raising the pins Balternately as the ends of said lever are alternately raised, thehorse-power maybe conveniently and quicklyraised by one man to receivethe trestle, and securely held until sai-d trestle has been adjusted inplace.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- The combination of the slotted perforated post A, twopins B, lever C, and chain D, with each other, said parts beingconstructed, arranged, and operating substantially as herein shown anddescribed, and for the purpose set forth. i

ANDREW KRIEBEL.
